PC Mount 9-Pin Tube Socket Layout

Loren42 · 13th July 2010, 12:53 AM

Can anyone confirm the layout dimensions for a standard 9-Pin tube PC socket?

It looks like 9 hole pattern is grouped in a circle diameter of 21 mm to me.

Bleh, I had the reply tready but hit close button by accident

Anyway, there is no such thing as a "standard 9-pin tube socket". I have two different types of noval 9-pin socket here, the smaller one (included in Eagle tubes.lbr library) and the larger one (which I had to add to the library myself).

Pins are spaced equidistantly (with 10th pin missing, obviously) around the circumference of a circle with diameter of 17 mm (smaller, plastic socket) or 21 mm (larger, "ceramic" socket that can be found on eBay quite cheap from Chinese sellers).

Since pins will wiggle a bit they can easily fit onto standard 25 mil (or was it 50 mil ? not sure but I think it's the former) routing grid to allow for easier PCB routing. If you need pin coordinates so you can draw your own socket layout, let me know and I'll look them up.

I can do the layout, just wondered if the JPEG I listed in my first post was typical for a 9-pin socket or if every socket manufacturer are wildly different.

Just need something to get started.

I'll check the Eagle library for another data point.

Thanks!

It appears to match the "ceramic" sockets Chinese are selling on eBay.

The Eagle library 9-pin has a diameter of 0.673" (17.1mm), so that doesn't give me a warm fuzzy.

That's precisely what I told you above, those only fit the smaller (plastic) sockets that I also happen to have. I had to create my own footprint that fits the larger sockets. Both noval and PCB mountable, but different dimensions ...
